Researchers have studied the concepts of optimism and pessimism as traits, expectations, strategies, and styles of explaining outcomes. Explanatory style and the strategy of defensive pessimism are two of these areas. In general, optimistic...

The purpose of this study was to determine if training has a protective effect on endothelial function following the consumption of a high-fat meal. Twenty young males classified as trained or untrained underwent vascular and blood lipid testing...

In a printing ink plant, phthalocyanine (Pc) aqueous slurries are produced by grinding the Pc pigment in water using a media mill. Mostly, dispersions of Pc in water are used in heat-set printing inks to make the color phthalo blue. Typically, Pc...

Many businesses have poor IT infrastructure and are in need of a major overhaul. University of Louisville Properties (ULP), in particular, needed the ability to share files between staff, backup data, secure data, and eliminate viruses and malware....

Low-trauma fractures of older women are a major public health burden. Fractures of the hip and spine are some of the primary causes of chronic pain, functional impairment, and disability among the elderly [1]. The underlying cause of these...

Richard Florida's (2002a and b) work ranks 276 U. S. Metropolitan Statistical Areas (MSA) according to a creativity index. This dissertation explores whether the creativity index or its subcomponents are related to the economic strength or growth...

This research will look at a printing operation that prints labels for paint cans. This particular printing operation is a multi-product, single-machine system with stochastic demands that uses a printing press to print the labels on large sheets...

Outerplanar graphs are planar graphs that have a plane embedding in which each vertex lies on the boundary of the exterior region. An outerplanar graph is maximal outerplanar if the graph obtained by adding an edge is not outerplanar. Maximal...

Peer-to-peer networks have been growing in popularity over the past decade. There have been many new innovations that greatly improve access to a wide variety of content. This expanded capability combined with a strong sense of anonymity has given...

Arrow's classic theorem shows that any collective choice function satisfying independence of irrelevant alternatives (IIA) and Pareto (P), where the range is a subset of weak orders, is based on a dictator. This thesis focuses on Arrovian...

The area of total coloring is a more recent and less studied area than vertex and edge coloring, but recently, some attention has been given to the Total Coloring Conjecture, which states that each graph's total chromatic number xT is no greater...

The Combinatorial Nullstellensatz can be used to solve certain problems in combinatorics. However, one of the major complications in using the Combinatorial Nullstellensatz is ensuring that there exists a nonzero monomial. This dissertation looks...

A connected matching in a graph is a set of disjoint edges such that, for any pair of these edges, there is another edge of the graph incident to both of them. This dissertation investigates two problems related to finding large connected matchings...

Given a metric space (K, d), the hyperspace of K is defined by H(K) = {F c K: F is compact, F ≠ 0}. H(K) is itself a metric space under the Hausdorff metric dH. Hyperspaces have been extensively studied by topologists since the 1970's, but the...

Development of microscale actuating technologies has considerably added to the toolset for interacting with natural components at the cellular level. Small-scale actuators and switches have potential in areas such as microscale pumping and particle...

The classification of self-dual codes has been an extremely active area in
coding theory since 1972 [33]. A particularly interesting class of self-dual codes
is those of Type II which have high minimum distance (called extremal or...

High dynamic range imaging involves imaging at a bit depth higher than the typical 8-12 bits offered by standard video equipment. We propose a method of imaging a scene at high dynamic range, 14+ bits, to detect motion correlated with changes in...

Previous research on organizational mergers has found that such a business activity bears an effect upon the structural and cultural foundations of organizations. Whether combining intellectual resources or capital, mergers combine workforces that...

The field of graph theory has been indubitably influenced by the study of planar graphs. This thesis, consisting of five chapters, is a historical account of the origins and development of concepts pertaining to planar graphs and their...

The topic of this dissertation is the automation of the process of extracting understandable patterns and rules from data. An unprecedented amount of data is available to anyone with a computer connected to the Internet. The disciplines of Data...
